Panel Indicators

Panel indicators are lighting devices used to indicate the status of a system or process, such as the operation of a machine, the correct functioning of a circuit or the presence of an alarm situation. Common applications include signally the need for maintenance, indicating the operational status of circuits, and displaying alarm events.

Panel indicators typically feature a metal housing, an electrical connection, and a light source. The metal housing is designed to either mount directly or be placed into metal rings. The electrical connection can consist of either a plug or a screw in order to access to the power source. The light source often consists of short terminals, an LED, or an illuminating bulb.

Pilot Lights

Pilot lights are specialized indicator lights used to provide visual feedback in a variety of industrial and commercial applications. The most common use for a pilot light is to indicate whether a system is powered on or off; other applications for this type of visual signal include indicating the presence or absence of a particular type of fuel such as natural gas.

Pilot lights are typically used in operations that require quick visual confirmation of a system\'s operating status; they can be used for representing the turning on or turning off of motors, compressors, pumps, and other machinery. Pilot lights can also be used to indicate when a system has overheated, or if there is a need for immediate repair and replacement of parts.

19091357 Application Field and Working Principle

The 19091357 indicator type is a two-way panel indicator typically used to signal overload, short circuit, or incorrect wiring conditions. It is also used to indicate an open connection or emergency power shutoff in systems powered by 220VAC or less. The 19091357 panel indicator is a compact unit designed for easy installation in tight spaces. It is capable of withstanding a great deal of vibration and shock due to its robust aluminum alloy housing and reinforced quartz cover.

The basic principle of operation of the 19091357 panel indicator is a red and green light signal that utilizes two single-pole, double-throw (SPDT) switches to indicate the status of the power output. The SPDT switches are wired in such a way that when the power is on the red light illuminates, and when the power is off the green light will illuminate. Additionally, each SPDT switch has an adjustable overload protection that will trip and deactivate the system if the power travels beyond a certain threshold.
